Multiplayer

This section of the wiki collects information on Mass Effect 3's cooperative multiplayer mode. Mass Effect 3's multiplayer supports up to 4 players at once and can only be played online. Multiplayer will affect the outcome of your singleplayer game. Your "Galactic Readiness" rating will determine the outcome of the final fight against the Reapers, though playing the multiplayer is not at all necessary to completing the single player story.

You can modify the color of your armor and other aspects of your appearance in Mass Effect 3's multiplayer. You cannot use your Shepard model to play multiplayer. You can also modify your Powers and Weapons.

You can buy upgrades including Weapons, Health packs and Ammo Packs in the Multiplayer Store. You can also unlock new characters in the store. To purchase items in the store you need Credits which you gain from playing multiplayer rounds.

Upon reaching level 20 with any multiplayer character, there is an option to promote that character. You gain approximately 10 war asset points to use in the single player campaign and your N7 ranking increases. However, the level of your character is reset to level 1. To promote a character, go into the character setting by clicking Y or triangle. Then highlight your level 20 character and hit either the X or square button to receive a promotion prompt.
